文摘

A nanocomposite of multi-walled carbon nanotubes (MWNTs) embedded in poly(ortho-anisidine) (POAS) and pure POAS were synthesised by oxidative polymerisation. Langmuir–Schaefer (LS) films were fabricated at air–liquid interface. The in situ doping process was performed during the film deposition itself by spreading chloroform solutions of the materials onto 1 M HCl. The specific conductivity of both the nanocomposite (POAS-MWNTs) and pure POAS was investigated to verify the effective enhancement provided by the insertion of MWNTs inside the polymeric matrix. The morphology of POAS-MWNTs nanocomposite films was investigated by atomic force microscopy. Evident relationship between the film morphology and its conducting properties was revealed.
